Peach tree named ‘AgriPeachOne’

ABSTRACT

A new and distinct mid-season peach tree cultivar (i.e.,  Prunus persica ) is provided that forms attractive highly blushed vertically flattened fruit. The fruit has semi-freestone white flesh that is sweet and juicy and of low acid content. The fruit commonly is larger and possesses slightly more red blush than the ‘N.J. F-2’ cultivar (U.S. Plant Pat. No. 5,123). Also, the fruit commonly matures at least three weeks later than the ‘N.J. F-2’ cultivar.

SUMMARY OF THE INVENTION

The present invention is directed to a new and distinct peach (i.e., Prunus persica) cultivar that originated as a chance seedling on the property of Agri Sun Nursery L.L.C. located at Selma, Calif. The peach seed used in the planting was harvested from an open-pollinated tree of the ‘N.J. F-2’ cultivar (U.S. Plant Pat. No. 5,123). The pollen parent (i.e., the male parent) is unknown.

The seed that produced the new cultivar of the present invention was planted in the late fall and winter of 1993. The first fruit was observed during 1995 and 1996. Had my efforts including the growing and study of the seedlings not have led to the discovery and preservation of the new cultivar of the present invention, it would have been lost to mankind.

It was found that the new peach cultivar of the present invention exhibits the following combination of characteristics:

(a) Forms highly blushed fruit having a vertically compressed oblate configuration,

(b) Forms fruit having semi-freestone white flesh that is sweet and juicy with a low acid content,

(c) The fruit commonly is larger and possesses slightly more red blush than the ‘N.J. F-2’ cultivar, and

(d) The fruit commonly matures at least eighteen to twenty-one days later than the ‘N.J. F-2’ cultivar.

The flattened configuration of the fruit is somewhat unusual. It is understood that peaches of this shape were discovered in China over 3,000 years ago, and are believed to have been introduced into the United States from Spain. In the early 1800's peaches of this general configuration are reported to have been grown by early settlers in the Midwest.

The new cultivar of the present invention exhibits a mid-season harvest date. The white flesh is crisp at harvest and can be classified as being semi-freestone since it breaks away easily from the pit. The skin is mostly dark red with some yellow. More red coloration is present with increasing exposure to sun during maturation. The crisp nature of the fruit at harvest enables it to ship well and to well tolerate routine handling procedures. The fruit also holds up well in storage and displays a good shelf life. The flavor at harvest is very good and possesses a very low acid level.

The new variety of the present invention readily can be distinguished from its maternal parent (i.e., the ‘N.J. F-2’ cultivar) by its substantially later maturity date, larger fruit, slightly more red blush on the fruit skin, and very sweet low acid flavor.

Asexual reproduction by budding at Selma, Calif., has demonstrated that the characteristics of the new cultivar are firmly fixed and are reliably transferred from one generation to another. Budwood was first collected from the original seedling of the new cultivar during the winter of 1996. Seedlings were budded early in the spring of 1997. The fruit was first observed on the resulting trees in July of 1998. The characteristics of the new cultivar were consistently displayed in the subsequent generation following such asexual propagation.

The new cultivar of present invention has been named ‘AgriPeachOne’ and is being commercially marketed under the JUPITER trademark.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show specimens of various plant parts of the new cultivar in color as nearly true as it is possible to make the same in color illustrations of this character. The plants were grown at Selma, Calif.

FIG. 1 illustrates specimens of the fruit and foliage during late July 1999 as the fruit approached maturity. The illustrated fruit having a vertically compressed oblate configuration was produced under growing conditions that experienced some shading during fruit maturation. Accordingly less red blush has developed than if the fruit had experienced more exposure to sun. Also, the red-brown coloration of the illustrated stone is the result of some darkening due to the exposure to air.

FIG. 2 illustrates specimens of the large showy blossoms during March 2001. The illustrated blossoms are in various stages of opening. It will be seen that the petal margins exhibit more lightening in coloration with age.

FIG. 3 illustrates a typical fruit during July 2000. The illustrated fruit was produced on a young tree of approximately four years of age and experienced more exposure to sun during maturation than the fruit illustrated in FIG. 1. Accordingly, the illustrated fruit exhibits more red coloration.

DETAILED DESCRIPTION

The following detailed description of the new cultivar was obtained through the observation of plants growing at Selma, Calif. The observed plants were approximately four years of age, and were grown on Nemaguard rootstock in the field under typical soil and weather condtions for the area. Color designations are with reference to the Color Name Chart of the Inter-Society Color Council, National Bureau of Standards. Common color terms are to be accorded there customary dictionary significance.

Botanical classification: Prunus persica, cv. ‘AgriPeachOne’.

Although the new ‘AgriPeachOne’ cultivar of peach tree possesses the above-described characteristics as a result of the growing conditions at Selma, Calif., it is to be expected that variations of the usual type and magnitude may appear that are caused by differences in growing conditions, fertilization, pruning, pest control and other horticultural practices when the new cultivar is grown in different environments.
